Maybe the girl was too sheltered. I can’t understand how any kid could feel so ashamed and embarrassed that they would commit suicide over it. Maybe this was the first time the kid ever was embarrassed about anything?
granted it was a pretty dumb thing she did. But not so dumb that she should end her life over it.
I think that you are missing a major part of the thinking behind what happened. This young lady thought that her body was her most important asset. She was essentially giving herself to this young man, who did not value her the way she hoped.
That is the sad part.
